Question 765872
x= 	Number of	adults						
y=	Number of	children						
 								
1	x	+	1	y	=	25	.............1	
Total value								
16	x	+	6	y	=	260	.............2	
Eliminate	y							
multiply (1)by		-6						
Multiply (2) by		1						
-6	x		-6	y	=	-150		
16	x	+	6	y	=	260		
Add the two equations								
10	x				=	110		
/	10							
x	=	11						
plug value of			x	in (1)				
1	x	+	1	y	=	25		
11		+		y	=	25		
				y	=	25		-11
				y	=	14		
				y	=	14		
x=	11		Number of	adults				
y=	14		Number of	children
